Application filed April 12, 19550.

'0 all whom may concern:

Ee it known that REGINALD Planer UR- WIN PARNELL, subject of the iiling; oir LGreat Britain and reianch residing at Number 3 rirangi Road, South Kiibirnie, veiling/ton7 New Zealand, have invented a new and use'fui i Lnox/ement in Vaporizers for fasoiine Engines; and do herebjvv deeiare the foilowing to be a full, dear, and exact description oi the saine.

This invention reiates to an improved means Vfor vaporizing iuei mixture for gasoline engines, and to means ifer controlling the same.

According hereto, a easingr member is inserted beneen the flanged ends ot the intake pipe leading 'from the a-.rburettei' to the `engine. in the central portion oi' the member an opening' by means oi which the mixture can pass through trein one portion ot' the intake pipe to the other portion. f heading` pipe from trie exhaust manifold nasses through the opening whereby the {'asoline particles, passing" through the member, are thorouginy ifaporized. rEhe ineinber is so termed to ensure that the 'fuel mixture xviii be directed on to the pipe thereby enleeting` better vaporization.

rEhe invention is illustrated in the aecomdrawings, in whiehz ,s injure l, is a diagrammatic View showing the Oenerai method or arrangement of the tiansije 5 et the induction pine (3 and secured between the two franges by bolts 'i'. The

centre it the member is prorided itha suitable opening' S and through this opening` Serial No. 373,207.

a heating pipe 9 is passed. This heating; pipe 9 is Connected to the main exhaust pipe l0 and after passing through the member l returns to the exhaust pipe as shown in Figi ure i. rthe opening' 8 has tongues ll and 12 converging towards the pipe 9 in order to direct the flow of mixture upon such pipe. The mixture passing,` from'y the earburetter to the induetion pipo passes around the heating pipe and is therebj,7 heated and y vaporized.

he flow oi exhaust gas through the pipe 9 i'nay if desired be Controlled by a valve i8 the plug of which is Connected to a lever a control rod 14 as shown in Figure l the end of the rod hav k a slot l5 passing; over a` boit 1G eontrolied by a thumb screw i7 upon a braeiet 1S fixed to the floor 19 of a motor ear.

What Claim is y ieviee of' the class described, the oomxi or a earburetter; an inlet manif tmd.. a inen'iber interposed between the carburetter and the inlet manifold having' a passage through which the mixture from the earburetter passes to the inlet manifold; an exhaust pipe; heating pipe Connected to different parts of the exhaust pipe and passing` through the passage in said member whereby the mixture from the eaiouretteris heated in said member; and opposite tongues formed on said member and extending into said passage for resti'ietingl the latter and directing,` the flow of the mixture over said heating pipe.

in testimony whereof, l have signed nw name to this specification in presenre oi tuo subscribing witnesses.
